What is carbon black mesh?
The mesh number is the unit that represents the size characteristics of the granular material, and the particle size of the powder is called the particle size. Due to the complexity of the particle shape (carbon black), there are usually several representation methods such as sieving particle size, sedimentation particle size, equivalent volume particle size, and equivalent surface area particle size. The sieving particle size is the size of the sieve holes that the particles (carbon black) can pass through the sieve, expressed as the number of sieve holes in a 1-inch (25.4mm) wide sieve, so it is called "mesh number".
What is the calculation method of carbon black mesh number?
At present, it is more popular in the world to use the calculated diameter of equivalent volume particles to express the particle size, with μm (micrometer) or mm (millimeter) as the unit. Carbon black mesh calculation method: 2 meshes correspond to 8000 μm; 3 meshes correspond to 6700 μm; 4 meshes correspond to 4750 μm; 5 meshes correspond to 4000 μm; 6 meshes correspond to 3350 μm; 7 meshes correspond to 2800 μm; 8 meshes correspond to 2360 μm; Mesh number corresponds to 1700μm; mesh number 12 corresponds to 1400μm; mesh number 14 corresponds to 1180μm; mesh number 16 corresponds to 1000μm; mesh number 18 corresponds to 880μm; mesh number 20 corresponds to 830μm; mesh number 24 corresponds to 700μm; mesh number 28 corresponds to 600μm; mesh number 30 Corresponding to 550 μm; 32 mesh corresponding to 500 μm; 35 mesh corresponding to 425 μm; 40 mesh corresponding to 380 μm; 42 mesh corresponding to 355 μm; 45 mesh corresponding to 325 μm; 48 mesh corresponding to 300 μm; 50 mesh corresponding to 270 μm; 60 mesh corresponding to 250 μm ;65 mesh corresponds to 230μm;70 mesh corresponds to 212μm;80 mesh corresponds to 180μm;90 mesh corresponds to 160μm;100 mesh corresponds to 150μm;115 mesh corresponds to 125μm;120 mesh----120μm;125 mesh corresponds to 115 μm; 130 mesh corresponds to 113 μm; 140 mesh corresponds to 109 μm; 150 mesh corresponds to 106 μm; 160 mesh corresponds to 96 μm; 170 mesh corresponds to 90 μm; 175 mesh corresponds to 86 μm; 180 mesh corresponds to 80 μm; 200 mesh corresponds to 75 μm; 230 mesh corresponds to 62μm; 240 mesh corresponds to 61μm; 250 mesh corresponds to 58μm; 270 mesh corresponds to 53μm; 300 mesh corresponds to 48μm; 325 mesh corresponds to 45μm; 400 mesh corresponds to 38μm; 500 mesh corresponds to 25μm; 600 mesh 800 mesh corresponds to 18 μm; 1000 mesh corresponds to 13 μm; 1340 mesh corresponds to 10 μm; 2000 mesh corresponds to 6.5 μm; 5000 mesh corresponds to 2.6 μm; 8000 mesh corresponds to 1.6 μm; 10000 mesh corresponds to 1.3 μm.
At present, there is no unified carbon black powder particle size technical standard at home and abroad, and each enterprise has its own definition and expression method of particle size index. There are different standards for screen mesh specifications in different countries and different industries, so the meaning of "mesh" is difficult to unify, so the use of "mesh" is not reliable, and it is better to use less carbon black mesh when purchasing carbon black.
What can 1000 mesh carbon black do?
1000-mesh carbon black is still relatively fine, like 1000-mesh pigment carbon black, which has better dispersibility and is easier to disperse into the base material.
